Abstract

The utility model discloses a micro-centrifuge tube with an easy-open lid, which comprises a tube body. A tube lid is connected to the upper end of the tube body, a tube plug plugged inside a tube opening is arranged on the tube lid, a circle of projecting edge extending outside is radially disposed at the opening position of the tube body, and a projecting side which matches with the projecting edge mutually is arranged on the tube lid. The micro-centrifuge tube with the easy-open lid adopts a double-layer locking system to place the tube lid at the opening position of the tube body, thereby effectively preventing the tube lid automatically popping up during centrifugation at high temperature in high speed, preventing samples from being polluted by air even spilling out from the inside of the tube, achieving extremely reliable lid seal effect, and having capability of being widely applied to manufacturing of centrifugal tubes.

Description

A kind of easy-open end microcentrifugal tube

Technical field

The utility model relates to a kind of centrifuge tube, specially refers to a kind of easy-open end microcentrifugal tube.

Background technology

Microcentrifugal tube is one of the most frequently used device of fundamental sum in the experiment of life science, especially biology field.Because in the existing microcentrifugal tube design, the experimenter is when operations such as open pipe, finger or opener tend to touch inevitably the pipe close part, thereby cause the pollution of sample in the pipe.Particularly when DNA (DNA) was housed in the pipe, the sample after these are polluted made original sample changed beyond recognition behind process polymerase chain reaction (PCR).And at present, when at high temperature carrying out high speed centrifugation, the pipe lid of existing microcentrifugal tube can be opened automatically, thereby is polluted after causing sample to be exposed in the air, even spills in managing, thereby is difficult to meet people's instructions for use.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of easy-open end microcentrifugal tube.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of easy-open end microcentrifugal tube, comprise body, described body upper end is connected with the pipe lid, and described pipe covers to be provided with fills in the pipe close that is connected in the mouth of pipe, described body opening part is provided with the convex edge that a circle extends radially outwardly, and pipe covers and is provided with the chimb that cooperatively interacts with this convex edge;

As improvement of the technical scheme, be extended with left and right fillet on the convex edge of described body, left and right fillet is one-body molded with the pipe lid;

As further improvement in the technical proposal, be extended with the flanging between left and right fillet on the chimb of described pipe lid;

Further, be extended with on the chimb of described pipe lid and draw the limit.

The beneficial effects of the utility model are: this product adopts double-deck fastening system will manage the opening part that lid is arranged on body, thereby the pipe lid automatically springs open when effectively preventing high temperature, high speed centrifugation, avoid sample to be subjected to the pollution of air even in managing, spill, the capping effect is very reliable, can be widely used in the making of centrifuge tube.

Description of drawings

Following accompanying drawing further specifies the utility model.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the utility model is by the structural representation that opens state;

Fig. 3 is the structure cut-away view that the utility model closes the state that closes.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of easy-open end microcentrifugal tube, comprise body 1, described body 1 upper end is connected with pipe and covers 2, described pipe lid 2 is provided with plug and is connected on the interior pipe close 21 of the mouth of pipe, thereby constitute the first tight lock system, described body 1 opening part is provided with the convex edge 11 that a circle extends radially outwardly, pipe covers 2 and is provided with the chimb 22 that cooperatively interacts with this convex edge 11, thereby this design constitutes the second tight lock system, and this design prevents effectively that also experimenter's finger or opener from contacting with pipe close 2.

This product is extended with left and

right fillet

12,13 on the convex edge 11 of body 1, left and

right fillet

12,13 and pipe covers 2 one-body molded, thereby guarantees that effectively pipe cover 2 when open mode, manage cover 2 and body 1 keep in touch, prevent loss.

In addition, be extended with the flanging 23 between left and

right fillet

12,13 on the chimb 22 of described pipe lid 2, and, be extended with on the chimb 22 of described pipe lid 2 and draw limit 24; The design of flanging 23 and La Bian 24 has guaranteed that effectively the user uses one hand to push flanging 23 or lift and draws limit 24 all pipe can be covered 2 and opens, so very convenient in the use.

This product adopts double-deck fastening system to manage to cover 2 opening parts that are arranged on body 1, thereby pipe covers 2 automatically spring open when effectively preventing high temperature, high speed centrifugation, avoid sample to be subjected to the pollution of air even spill in managing, the capping effect is very reliable, can be widely used in the making of centrifuge tube.
